In 1989, Nicolas Bartholomew created Musica ISDN - which he is now detached from - a company dedicated to the recording and post-production of classical music. The company has since made hundreds of records and became, in the late 90s, one of the most prolific executive producers, serving a large number of phonographic publishers.
In 1999, he founded Ambrosia - now owned by Naïve - a label he ran for ten years with enthusiasm by getting involved in the launching young talent. In 2008 he recreated the recording studio 'Little Tribeca', as well as a new label: Aparté.
